DISK FURROW-OPENER.

SPECIFICATION forming part of Letters Patent No. 744,711, dated November24, 1903.

Application filed March 28, 1903.

To all whom, it may concern:

Be it known that I, WILMONT BILLS, a citizen of the United States,residing at the city of Dowagiac, in the county of Cass and State ofMichigan, have invented certain new and useful Improvements in DiskFurrow-Openers, of which the following is a specification.

This invention relates to improvements in diskfurroW-openers. Itisparticularlyadapted for use in grain-drills, although desirable for usein other relations.

The objects of the invention are to provide an improved diskfurrow-opener in which the disks are satisfactorily cleaned and thecollection of soil and trash prevented.

A further object is to provide an improved scraper mechanism for diskfurrow-openers in which the tension can be quickly and easily adjusted.

Further objects will definitely appear in the detailed description tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is fully illustratedin the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a detail side elevation view of a double-diskfurrow-openerembodyingthefeatures ofmy invention, portions being brokenaway to show the arrangement of the parts. Fig. 2 is a detail sectionalview taken on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail sectionalview taken on lines 3 3 of Figs. 1 and 4. Fig. 4 is a detail View takenon line 4 4 of Fig. 3. Fig. 5 is a detail sectional view taken on Fig. 6is a detail plan view showing the spring-pressure connection for thescraper-blades F for the inner faces of the disk, and Fig. 7 is a planView of one of the scraper-blades F.

In the drawings the sectional views are taken looking in the directionof the little arrows at the ends of the section-lines, and

similar letters of reference refer to similar SerialNo.150,07 l. (Nomodel.)

ings, the boot A is of the usual or any desired form. The bearings forthe disks B 13, also of any desired. form, are carried by the boot.

Projecting forwardly from the boot A is a bracket A, to which thedraw-bar A is secured. On each side of the bracket A are projecting lugs(0, which are provided with suitable hearings to receive the journals ofthe brackets O, by which the scraper-blades are supported. The scrapersD are adapted to rest against the outer faces of the disks. Pressure isapplied to these scraper-blades by blade-springs O C, which are securedat one end to the brackets O and are adjustably secured together at theopposite end by a link E, into which the bolts 6, which are passedthrough the ends of the springs, are threaded. The bracket A is providedwith a suitable perforation or opening E, through which the link Eextends, so that the tension upon the scrapers D is capable of completeand easy adjustment and the tension on the two blades is equal at alltimes.

The blades D are pivotally secured to the brackets O by heads cl, whichare journaled upon the pivot c of the bracket 0. These heads d arepreferably formed of malleable iron with extending lugs at each side, sothat the scraper-blade may be placed in position and the lugs hammereddown upon the same, as clearly appears in l and 4. They are alsoprovided with a lug at f, which is adapted to engage the flange 0 toretain the head upon the pivot. By this structure the parts may beproduced very economically and they are conveniently and economicallyassembled, and should the blades D become worn new ones may be readilyinserted. By this arrangement of parts the blades are held against thedisks by a yielding pressure and are perfectly free to yield to anyobstruction, so that wear upon the same is reduced to a minimum and alsothe danger of breaking the supports.

The inner faces of the disks B are freed from soil, and the accumulationof trash is prevented by scraper-blades F, which project between thesame to the rear of the boot. (See Figs. 1 and 5.) These scraper-bladesF are supported-upon a bracket A, which extends rearwardly from the bootand areheld against the innerfaces ofthedisksbyspring-pressure. Thescraper-blades F are slotted at n to engage the pin g on the bracket Aand are pivotally secured together at their inner lower ends by asuitable rivet or the like g. Aspring 71, which is retained in positionby a pin it, engages suitable perforations in the upper ends of theblades F, so that they are held outwardly against the inner faces of thedisks. The spring 72 is formed in one place so that the scraper-blades Fare held against the disk with an equal pressure. Several perforations nare provided in the upper edges of the blades to engage the spring 7t,so that the tension can be adjusted or the blades can be adjusted tocompensate for wear. This scraper is also very easy to construct andquickly assembled. In assembling, the ends of the spring h are engagedin perforationsin the upper ends of the blades, and the blades are swungdown between the disks onto the pin g and there retained by a suitablecotter-pin or the like. By this arrangement of parts the pressure isapplied to the scraperblades in a simple and satisfactory manner. Astructure is produced which is economical and durable.

I have illustrated and described my invention in the form preferred byme on account of its simplicity and economy in manufacture anddurabilityin use. I am aware, however, that it is capable of very considerablevariations in structural details without departing from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
